canines - maxillary Flashcards

1
Q

define the canine eminence

A
  • the alveolar bone over the maxillary canines bulges outward due to the shape of the root
  • contributes to our facial features
  • very thin bone

Q

define canine guidance

A
  • protection of the posterior teeth from potentially damaging horizontal forces by discluding the teeth in lateral movements
  • grind your teeth to understand this

Q

describe the maxillary canine, from the facial view

  • incisal tip form/position
  • cusp ridges
A

incisal tip/formation

  • in line with center of root
  • cusp tip is 105 degrees

cusp ridges

  • shorter on mesial ridge
  • also called “cusp incline”

Q

describe the maxillary canine, from the facial view

  • proximal outline form mesial
  • proximal outline form distal
A

mesial

  • broadly convex
  • convexity appears to be closer to the cusp, in the incisal 1/3

distal

  • usually a slight concavity in the cervical 1/3
  • convex in the middle 1/3
  • look for “distal stretch”

Q

describe the maxillary canine from the proximal view

  • heights of contour
  • crown surface form
A

heights of contour

  • facial and lingual are in cervical 1/3
  • more incisal than incisors

crown surface form

  • convex facial (straight as it approaches incisal tip)
  • S curve lingual
  • prominent cingulum

Q

describe the maxillary canine from the proximal view

  • cervical line form
  • cervical crown concavity
A

cervical line form

  • mesial curves 2-3 mm on average
  • distal line curves incisally less than mesial

cervical crown concavity

  • tendency toward a cervical crown concavity on both mesial and distal
  • larger on distal

Q

describe the maxillary canine from the incisal view

  • crown outline form
  • incisal edge form/location
  • cingulum
  • facial convexity
A

crown outline form
- a series of arcs

incisal edge form/location

  • incisal edge is straight MD
  • line bisects proximal arcs (greatest point of convexity)

cingulum

  • width coincides with the root positon
  • smaller arc than labial

facial convexity
- prominent middle labial lobe

17
Q

describe the maxillary canine root form

  • labiolingual root taper
  • longitudinal root depressions
A

labiolingual root taper
- more narrow from the lingual

longitudinal root depression
- usually more pronounced on the distal

18
Q

describe the maxillary canine root form

  • root curvature
  • proximal root outline form
A

root curvature
- may be a sharp curvature (M or D) to the root apex

proximal root outline form
- apical taper greater on lingual

teeth (2 decks)
